True Union球形止回阀，底阀和通风阀 PVC / CPVC / 聚丙烯 (PP) / Kynar (PVDF) True Union Ball Check, Foot, and Vent Valves PVC/CPVC/Polypropylene (PP)/Kynar (PVDF) 22oC温度下压力为150 psi，非冲击性水 150 psi at 73°F water–non-shock 特点 Features True Union连接装置允许在不中断连接管道的情况下拆卸阀门。连接管接头也可以与TU系列球阀和管道管接头进行互换。 True Union connections permit removal of valve with no disruption of connected piping. Union connections are also interchangeable with the family of TU ball valves and pipe unions. 通过用漂浮的PP球更换标准球，重力球形止回阀可以改造为适用于空气或气体排气口。然后倒置安装阀门，使得流体将球提升到阀座上。 Gravity ball check may be converted for air or gas venting by replacement of standard ball with floater PP ball. Then install valve upside down for fluid to lift ball into seat. 对于底阀，用一个F.V.滤网外壳组件更换进口连接管接头。 For foot valve, replace inlet end connection with an F. V. screen housing assembly. 在导翼中自由振荡的球有利于全流道流动，最大限度减小湍流和振荡。 Free oscillation of ball in guide ribs facilitates full port flow with minimum turbulence and chatter. 无论是泵的排泄口的排出压力，还是泵的吸入口，其流体止回的效果都是相同的。 Equally effective in checking back flows from head pressure on the discharge or suction sides of pump.

For 3" and 4" sizes of PVC and CPVC BC valves, replace U in the figure no. with S or T for socket or threaded units respectively. All sizes of PP and PVDF TUBC valves require stipulation of end connectors in their figure no.

除了阀体以外，所有部件都是可更换部件。 All components except valve bodies are available as replacement parts. 重力球形止回阀可以变为通风阀，只需用漂浮球体更换标准球体，然后在安装时将阀门倒置，使其阀座向上即可。 Gravity ball check valves are converted to vent valves by replacing the standard ball with a floater ball and inverting the valve at installation–with seat up. 每个更换件O形环组件包含所有O形环，满足整修任何True Union止回阀或球阀(无论是什么型号或类型)所需，或者最少包含两件管接头。 Each replacement O-ring kit contains all the O-rings required to refurbish any True Union Check or Ball Valve (regardless of model or style), or a minimum of two pipe unions. 重力球形止回阀可以变为底阀，只需在接受端口 - 阀体的阀座端口，用一个F.V.滤网壳组件更换管接头螺母和端口连接件即可。 Gravity ball check valves are converted to foot valves by replacing the union nut and end connector on the receiving end – seat end – of the body with an F.V. screen housing assembly. 聚丙烯，填充微量玻璃粉，称为GBPP。 Polypropylene, filled with glass micro-beads, is known as GBPP. FPM也称为FKM。这种密封式通过Viton或Fluorel品牌的橡胶模铸而成。 FPM is also known as FKM. These seals are molded from Viton or Fluorel brands of rubber.

所显示的尺寸适用于PVC和CPVC。由于模铸收缩，PP和PVDF的尺寸将会变得比较小，螺纹的端到端的长度与承插相等。 Dimensions shown are for PVC and CPVC. Due to molding shrinkage the dimensions for PP and PVDF would be somewhat less, and the end-to-end length of threaded equals socket valves. 可提供底阀滤网壳组件，用于现场更换通径DN15 - DN100的PVC和CPVC材质的TU球形止回阀。除了通径DN15 - DN50的PP和PVDF止回阀以外，对于任何通径的PP或PVDF阀门，都无法提供F.V.组件。 Foot valve screen housing assemblies are available for the field conversion of PVC and CPVC TU ball check valves in sizes 1/2" - 4". F.V. assemblies are not available for PP or PVDF valves in any size, and the PP and PVDF check valves are available in sizes 1/2" - 2" only. 表中所显示的重量适用于PVC螺纹连接的球阀。CPVC, PVDF和PP止回阀的重量可以在PVC重量上分别乘以1.123, 1.275或0.656。所显示的底阀重量实际上是适用于PVC材质的F.V.滤网壳组件。所以CPVC材质的F.V.滤网壳组件的重量可以将PVC重量乘以1.123而得。对于全部底阀重量，这些都必须加入止回阀中。 Weights shown for ball valve figures are PVC threaded models. For an approximation of CPVC, PVDF, and PP check valve weights the PVC weight may be multiplied by factors of 1.123, 1.275, or 0.656 respectively. Weights shown for foot valves are actually those for PVC F.V. screen housing assemblies. So, the weight for a CPVC F.V. screen housing assy. may be found by multiplying the PVC weight by the 1.123 factor. These must be added to check valve weight for full foot valve weight. Cv流量系数值是以多数阀门的铺设长度(G)为基础计算而得。 Cv values are based on the basic valve laying length (G). PVDF管道，连接件和阀门没有DN32通径。可提供DN32通径的PP螺纹止回阀，但是这种通径的承插和法兰PP止回阀无法提供。 PVDF pipe, fittings, and valves are not available in the 1 1/4" size. The 1 1/4" PP threaded check valve is available, but the socket and flanged styles are not available in this size. DN100的PVC和CPVC止回阀采用液状粘结剂装配而成，既不需要法兰，也不需要平头管嘴DN80阀门端口上的连接件。 The 4" PVC and CPVC check valves are fabricated by solvent cementing either reducing flanges or reducing couplings onto the ends of a 3" valve with plain-end nipples.
